摘　　要：通过对220 k V电缆的现场耐压方案的比较和计算分析,最终采用变频谐振的耐压方式,而且利用该试验设备的自身特点选取了串联谐振并联补偿的方法,通过多个电抗器的串、并联组合增加了试验设备的灵活性。通过该试验的开展,云网首次完成了220 k V长距离电缆的现场交流耐压试验,证实了采用并联补偿、串联谐振的试验方法对电缆进行交流耐压是可行有效,试验方法和结果对今后相关试验的开展具有重要指导意义。By comparing and analyzing the withstand voltage scheme of the 220 k V cable, the frequency conversion resonance method is adopted, in addition, the series resonant parallel compensation method is selected by using the test equipment, and the flexibility of the test equipment is increased by series and parallel combination of multiple reactors. Through the test, Yunnan Electric Power completed the first field AC withstand voltage test of 220 k V long distance cable, it is proved that the method of parallel compensation and series resonance is feasible and effective. The test methods and results have important guiding significance for the future test.
